Core Skills
Grouped by the systems I build and operate most often.
Messaging
Kafka, JMS, asynchronous workflows, retry strategies, dead-letter queues
Cloud
AWS, GCP, Docker, Kubernetes, Helm, CI/CD, blue-green deployments
Databases & Observability
PostgreSQL, Oracle, Redis, Prometheus, Grafana, ELK, tracing
Architecture Case Study
Recovery paths, event flow, and failure handling in distributed workloads.
Distributed Event Processing Recovery Workflow
A generalized Kafka-driven recovery pattern based on the event processing platform work: ingestion, fan-out, retry isolation, dead-letter handling, and operational visibility.

PR Intelligence Platform Review Flow
Event-driven review orchestration from pull-request ingestion through analysis, persistence, and resilient result delivery.
- Ingestion Pull request metadata enters a Spring Boot API and is persisted before dispatch.
- Dispatch Kafka events trigger asynchronous review jobs without blocking the intake path.
- Analysis Rule engines and AI-assisted analyzers produce findings, recommendations, and status changes.
- Resilience Failed jobs are retried with status tracking, while review history remains queryable through APIs.

Experience
Built for scale in financial systems and high-traffic commerce.
Software Engineer
Built low-latency fund transaction and reconciliation services with Java, Spring Boot, Kafka, JMS, Oracle, PostgreSQL, Docker, Kubernetes, Jenkins, and AWS.
- Improved platform throughput by 40% through event-driven transaction pipelines.
- Reduced database query latency from 3.2s to under 1.1s in production.
- Enabled operations teams to resolve breaks 35% faster with workflow dashboards.
Software Engineer
Delivered backend systems for large-scale checkout and payment flows using Java, Spring Boot, Kafka, Cassandra, MySQL, Redis, Elasticsearch, Docker, Kubernetes, Jenkins, and GCP.
- Improved payment success rate by 12% with smart-retry payment orchestration.
- Reduced end-to-end API latency by 35% through performance tuning.
- Cut infrastructure overhead by 22% via scaling and cloud optimization.
